This silicone mould for casting crystal resin or Jesmonite, with 12 different types of pendants, is reusable. Castings from the moulds make lovely resin or stone-effect jewellery, or decorations. To extend the mould's lifespan, we recommend applying a release agent to it before pouring. The mould contains various sizes of squares, rectangles, an oval, a circle, as well as a puzzle piece and a droplet.
